Precautions for Use* Do not use this product without carefully reading the attachedowner’s manual.
* Do not turn the oil inlet screw located at the bottom of themain unit.
* Ensure that sufficient mounting strength is secured for thisproduct. (As a guideline, it should be 2 to 3 times the maximum
drag listed in the catalogue.)94* Do not use this product in a vacuum or a location where it
may come in contact with oil.
* Ensure that an eccentric load is not applied to the soft absorber.
(Allowable eccentric angle: ±2.5°) Allowable eccentric angle inFK-2050 and 2550: ±1.0°* Urethane caps are consumable goods that need to be replacedwith new ones if necessaryAdjustable type Self-adjusting

When attaching the eccentric angle adaptor, screw it into the main unit until the cap for eccentric angle andthe piston rod form a tight connection. While maintaining this position, fasten the main unit’s nut until secured.
* If the eccentric angle adaptor is secured without establishing a tight fit, a sufficient stroke cannot beobtained. Furthermore, if the eccentric angle adaptor is further screwed in, after it has formed a tightconnection, and then secured in place, the cap for eccentric angle cannot be pushed all the way to thestroke end.
● The inclined adapter is not available for models with soft absorber cap (-C) and urethane cap (-R)

2) Keep the cables as short as possible when using in places with a lot of noise.
Also, please take all precautions, such as avoiding the parallel wiring ofelectric lines and power lines, as well as wiring within the same conduit.
3) Ensure that the switch does not come in direct contact with thinner-type chemicals.
4) Because it does not have a short-circuit protection circuit, wiring must be done correctly.
